I liked..
e2> E3>Plutonia>E1> Doom2>E4>TNT
E4 I didnt get the story behind and it was very stiff gameplay.
note on doom 2,the first 2 thirds were ok and stand in order as they are but the last third was on par with e3.

Leave him alone. It does look very professional.you need an enthusiastic programmer tho. Yeah alot of people on doomworld have low self esteem and like to put other people down.
Here are my sugestions.
- Hexen ported instead of making your own engein, plese.
- A built in version of doombuilder using the stylus, plese.
- Doom 1 style play instead of 64, plese.
- wad format exactly the same,so you can put wads you like and play them, plese.
- skulltag multyplayer port, plese.
